I am beginning to think New Zealand has never in the past built ships independently and are going through a natural period of time of learning the ropes, so to speak. It appears from the new completion schedule the IPVs will be commissioned practically on time, whereas the OPVs and the MRV will be commissioned somewhat later.
The only ship that has been commissioned before independently has been the Endeavour, a ship without any armament or much crew. The MRV on the other hand is about the same size, does have some armament, a small crew, but with much more to fit, the army's quarters, their galley, and a large vehicle deck with new fire supression systems the navy is unfamiliar with. Therefore, its gonna take more time to learn the ropes, even with a ship that's not that high tech.
On top of these items, the computers systems aboard the new Project Protector vessels are twenty years newer than the Endeavour, and ten years newer than the Anzacs frigates.
In conclusion, while these ships are high tech to most nations, they are a challenge for the very small nation and navy of New Zealand. This project is also a challenge in growth numbers, and finding the right number of personnel with the required training to fit out the ship with the right personnel.
Sea Toby, while you are right in part, remember that the MRV is being fitted out by a contractor that does have experience in such matters.
New Zealand also has experience in the ANZAC ship programme.
So while I could accept personnel shortages as a reason for delay, the complexity of fitting out the MRV, is not, IMO, an excuse at all. The NZDF has historical experience of fitting COTS systems to its platforms and should be able to manage this fit out easily.
If we look at this from an Australasian point of view there is no real complexity here.
